我可以在powershell脚本中使用Resource.Schema.Mof文件中的数据吗？

我正在编写一个DSC资源，用于管理Windows DNS配置项（BootMethod、EventLogLevel等）。My

Get-TargetResource

函数需要迭代资源能够管理的所有配置项。目前，我在

Resource.psm1

文件中有一个哈希表来描述所有这些，但我希望能够使用

Resource.Schema.Mof

文件中已经存在的描述，这是构建资源的第一步。这是可能的，还是因为我不知道的原因而不明智

Schema.mof：

[ClassVersion("1.0.0"), FriendlyName("GO_DnsServerConfig")]

您可以尝试使用PowerShell v5中引入的类编写资源。它应该可以在很大程度上消除您所谈论的问题—例如，没有schema.mof可使用

您可以发布您的模块代码或其片段，以及mof的相关部分吗？谢谢，但我很难找到Resource.schema.mof中已经存在的描述，我看不出你想在代码中的什么地方重用这个值。你能指出你将在哪里重复描述吗，你在哪里；I’我希望定义一次吗？Schema.mof文件中的所有内容都将在$ConfigItems哈希表中进行第二次定义，以便我可以对其进行迭代并获取实际值。我希望能够读取Schema.mof数据来代替哈希表。哦，我想我明白你现在说的了。你考虑过做相反的事吗？根据脚本？生成MOF文件。嗯，这会增加一个构建步骤，我宁愿避免。在.Net中似乎必须有一些函数来解析.Mof文件。我只是不知道它是否是公共的。你能发布你的模块代码，或者它的一个片段，以及MOF的相关部分吗？谢谢，但是我很难找到“Resource.Schema.MOF中已经存在的描述，我不知道你想在代码中的什么地方重复使用该值。你能指出你将在哪里重复描述吗，你在哪里；I’我希望定义一次吗？Schema.mof文件中的所有内容都将在$ConfigItems哈希表中进行第二次定义，以便我可以对其进行迭代并获取实际值。我希望能够读取Schema.mof数据来代替哈希表。哦，我想我明白你现在说的了。你考虑过做相反的事吗？根据脚本？生成MOF文件。嗯，这会增加一个构建步骤，我宁愿避免。在.Net中似乎必须有一些函数来解析.Mof文件。我只是不知道其中是否有公开的。
